The invention concerns a system for evaluating vehicle, drive and operation parameters of a vehicle to select and adjust by means of a microprocessor a speed ratio of a gear according to predetermined calculation rules, characteristic values and characteristic fields wherein an acceleration of the vehicle is mathematically calculated from a number of revolutions of a drive train comprising engine and gear, the number of revolutions corresponding to the driving speed. The problem is to provide for different gear types a uniform system which requires only a few parameters adapted to the vehicle for selecting speed ratio and gear shift. This is attained by the fact that a minimum dwelling time (&Dgr;t,) is associated to each speed ratio range. To each change of speed ratio (i,) is further associated an adjustment time (&Dgr;t,) which in the average is required for the gear to complete a speed ratio change (&Dgr;i,). From the minimum dwelling time (&Dgr;t,) and the adjustment time (&Dgr;t,) is calculated, taking into account the vehicle acceleration (a), a change in number of revolutions (&Dgr;n,, &Dgr;n,) of the engine during said times. The speed ratio change (&Dgr;i,) to be carried out is calculated from a set number of revolutions (n,) or a gear shift number of revolutions (n,), and is carried out when the real number of revolutions (n,) reaches or exceeds the gear shift number of revolutions (n,)

A continuous closed-system process for the environmentally friendly drying and purification of benzanthrone which comprises the steps of charging a benzanthrone-containing paste of pumpable consistency onto a melt held in a stirred kettle, dewatering and melting the paste by means of steam, condensing the water vapor emerging from the stirred kettle, flaking the melt from the stirred kettle by means of a rotating drum, and packaging the flaked solids.

Board-shaped articles are to be stacked in a frame in such a way that they can be introduced into the frame from the same elevation, means being provided to ensure the maintenance of the desired spacing between the individual articles. To that end the spacing elements are supported in the frame in such a manner as to be deflectable and the articles during insertion deflect the spacing elements in the loading direction. The spacing element which is closest to an article already inserted comes into contact with such article.

Device for stacking board-staped articles

A crankshaft which is composed of a plurality of individual elements. Each of said elements comprises a crankshaft section with an end face and bearing surface means and also comprises a main shaft journal section with an end face and with bearing surface means. The end faces of pin sections to be connected to each other are electron beam welded together after centering pins have been inserted in bores arranged in, and perpendicular to the end faces to be welded together.
